Michael Ashcroft, the Conservative Party treasurer applauds at the Conservative Party conference in Blackpool, northern England, in this file photograph dated October 7,1999. A billionaire lord who has restyled himself as a pollster is providing Britain with unprecedented information about battleground constituencies ahead of a national election on May 7, 2015 potentially influencing some decisive races. A self-made business tycoon who donated over 10 million pounds ($15 million) to the ruling Conservatives in the past, Ashcroft has spent millions on non-partisan polls in "marginal" seats where there is a tight race between two or more parties, and is giving away the information gathered for free.
